fo (L ZZwhmn/itmoz/concern: A I Be it known thatwe, ELIAS B.` ALLEN, I g CHARLESIO. SMALL, and ALoNzo PrSMALL, of Augusta, in I the county of Kennebec and I State of VMaine, have inventeda new and useful Machine for Coiling Wire; and we `do here- ,I `lloyydeclare the following tobe a full, clear, and I exact descriptionI thereof, which will 1 enable Iothersto make andII useour invention, refer- 4ence beinghadtotheaccoinpanying drawings,

forming part of this specication, in which- I I Plate l isanexterion sideelevationof one `side ofa machine exhibitingour invention. Plate2 is a frontend elevation of the same.

The operating partsof our machine are set l In l, idly attached thereto, isfthe gear b, matching Ithelargergear @,which` latter is Irigidly attached to the shaft d. IUpon this Shaft are set IIthe two camsefe". Inl thePlates 3 and 4 is seen the formof Ithe paths of said cams, and

I therein are IIalsojillustratedI those portions of our? machine to which the said cams impart I motion, I In Plate 3 the rod f is provided with da smallstud, g, which fits into the path of the l cam.I I This rodis `supported or suspended in I positionby thebarh, pivoted to the inside of the frame ofthe machine at t', and allowing of II the horizontal `motion of the rod fas impelled ,":by themovement of thecam.` The otherend `oftherod is `providedwith a bolt, j,`which This bolt e is pivoted to theinside of the Vframe of the IImachineIat mand is providedlwith teeth a,

y which match theteethofthe pinion o, which pinionrevolvesthe gearp, matching with theI I` smaller gear q ontheshafton This shaft car- `ries and rotates thehoop s. I The shafti1 is hollow a portion of its length for the insertion of the wire to be coiled, which wire passes up overthe hoop, as illustrated in Plate 2.

The method of coiling the Wire willvherein'- after be more fully explained when certain other portions of the machine havefirst been described; but it may here be observed `that by the rotation of the cam e an intermittent reciprocating motion is imparted to thesector Z, the said sectorV remaining stationary when 'the stud g isy at that point in the path of the cam shown in Plate 3. It may also be observed that the rod f is adjustable or extensible, being made in two pieces, `and being furnished with the sleeve a and the right and left hand screws, as illustrated, the purpose of which arrangement is to regulate the distance of the movement of the sector Z, and

.the consequent number of revolutions of the hoop si The cani operates the points upon which the wire is coiled. of the came', which is different from the cam e, is illustrated in this figure; but the bar h', the rod f', thesleeve u', the boltj, and the slot kare the same as the devices already alluded to, and shown in plate 3, and need not be further described. B'y the revolution of this cam e a motion is imparted to the pivoted lever Z similar to that imparted by the cam e to the sector Z, but taking place when the sector is at rest. This lever Z is pivoted at In", and has the two horizontal arms n a. Pivoted to the ends of these two arms are the rods o p', adjustablelikef. Attached and pivoted to the ends of o' p are the inclined sliding arms q if', which move alternately through theguides s.` Upon theends of these sliding arms are the ceiling-pins t', Plate 2. By the revolution of the 'cani e the coiling-pins t t are alternately presented to the tongue t of the hoop s in order to receive the wire t. When one is thus presented. the other one is drawn back, as illustrated in Plates 2 and 4. This operation takes place when the stud g is atv the points designated by 1 and` 2of the cam e. In Plate l is seen a cam, w, set upon the end of the shaft cZ, onl the outside of the machineframe. This moves an arm, x, having at the end thereof a recess, y, and aprojection, y', and pivoted at z. The movement of the (See Plate 4.) The form arm x is inward and outward on a pivot-that is, when. the parts 3 and 4 of the cam w are in the recess y the end next to the cam w moves outward slightly, and the reverse is true when either of these parts are on the projection y. This arm .t operates the vertical lever 5, pivoted at G, in such manner as to push the plate 7,'Plate 2, out to the end ofthe coilingpins t and when thus pushedout, and when the points 3 or 4, Plate l, are in the recess y, the plate 7 is drawn back by the spiral Sto the position shown in Plate 2. The object of this movement of the plate 7 is to push the coils of wire off the coding-pins after the coil is formed, and thus to make way for the next succeeding one.

a shows a shaftupon which is set the channel-wheel b', to wind up the coiled wire ai'ter it passes from the coiling-pins. It has a i'ric tion-pulley, c', to receive a belt from either of the shafts d or a, and the revolution can be adjusted by means of the adjusting-nut d in such manner that when the wheel b would otherwise draw the coiled wire too fast the pulley7 c will slip round upon its shaft andthe the hoop s. As before described, the wire t' to-be coiled passes up over the hoop, under the tongue o, down to the ceiling pins. one ot' which is always advanced to receive the wire while the hoop rotates. Uien in this posi tion, thc hoop revolves in one direction and produces the desired number of coils of the wire around the pin thus advanced. The hoop then pauses, during which time the pin that has received the coil is drawn downward and the other one is elevated and another coil of the wire made around it hy amove'ment of the hoop in an opposite direction from that in which it rotated when makingthe previous coil. It will be seen that the distance between the coils is the distance between the pins. W'hen ciiher of the two pins is drawn downward with the coil upon it, the plate 7 advances and pushes the coil off, and thus prepares the pin to receive the next coil. As fast as it thus passes from the ceiling-pins it is wound up on the channel wheel or drum b', as before described.

That we claim as our invention, and desire to secure by Letters Patent, is

l.y The combination ofthe cani c, the rod f, sector Z, pinion and gear o p, the Q;ear and. hollow shaft q i', and the hoop s, together with the pins t t, substantially as described.

2. The combination ot the cam c', rod f and lever Z', the rods o', p. g', and r', coilingpins t', and the hoop s, subtantially as described. Y

3. The winding-shaft c', with its drum b and friction-pulley c', as described, in combi nation with the hoop 8 and the ceiling-pins t' t'.
